advice for 23

give me the best advice for someone who’s 23, lost, and has only focused on relationships and battling their self worth and respect. i keep making dumb decisions and putting myself in situations that ill get hurt in, and i keep telling myself its okay because it wont matter in a few years and ill learn from it. Anyways for some reason thats all ive focused on and now i genuinely feel like a loser. Like obviously my life isnt on pause but im definitely not putting as much energy into myself as i want to but no matter how many times i get this motivational hit, i root back to my old self.
